NighthawkRAX54 not connecting after only 3 months. ???? What now??? Thanks

You didn't really give us much to go off. 

Everyone has pretty valid questions that seek more clarity. 

The more you tell us, the better we can help you. 

1. what firmware is on it? 

2. what modem/gateway is it connected to? 

3. what do you mean it won't connect? Won't connect to the modem? Devices won't connect to the wifi? Will connect to the wifi but don't have an internet connection? Won't connect to wired devices? 

Details are key in helping out on online forums. So go into depth. 

You also put that its only 3 months old. Netgear does have 90 days of free support. If you're within that 90 days, you could contact support for free for help.
